Answer:
67 degrees
Step-by-step explanation:
180-127= 53
angle BAC= 53
60 +53= 113
180-113= 67
angle ACB= 67 degrees
The time that will be taken for Daniel to swim to the boat ramp will be 3.34 minutes.
<h3>How to calculate time taken</h3>
Let the distance be x.
Based on the information given, the calculation will be:
Sin 53° = 400/x
0.7986 = 400/x
x = 500 feet
Time = Distance / Speed
Time = 500/150 = 3.33 minutes.
The distance of the boat ramp from the campsite will be:
Cos53° = y/500
0.60 = y/500
y = 300 feet.
Distance will be:
= 1600 - 300 = 1300 feet
The minutes that it takes him to jog from the boat ramp to the campsite will be:
Distance = 1300 feet
Rate = 4 miles per hour = 352 feet per minutes
Time = Distance / Rate
Time = 1300/352 = 3.69 minutes
The total time taken will be:
= 3.33 + 3.69
= 7.02 minutes

Answer:
0.8 s
Step-by-step explanation:
Horizontal velocity
= 61cos(35) = 49.968 f/s
To reach 40 feet, it takes
40/49.968 = 0.801 = 0.8 sec
